High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
• This signal will be output when the frequency reaches the level set in the frequency settings (F001,
A020, A220, and A320) or the multi-step speed settings (A021 to A035).
• Set the Multi-function Output P1 to P5 Selection (C021 to C025) or the Multi-function Relay Output
(MA, MB) Function Selection (C026) to 01 (FA1).
• FA2 will be output when the output frequency exceed the Arrival Frequency During
Acceleration/Deceleration 1 (C042/C043); FA4 will be output when the output frequency exceed the
Arrival Frequency During Acceleration/Deceleration 2 (C045/C046).
• Set the Multi-function Output P1 to P5 Selection (C021 to C025) or Multi-function Relay Output (MA,
MB) Function Selection (C026) to 02 (FA2) or 24 (FA4) to allocate the desired signal.

(Example)
Max. frequency f
max=120 [Hz]
Set frequency f
set=60 [Hz]
Hysteresis at power ON:
f
on=120×0.01=1.2 [Hz]
Hysteresis at power OFF:
f
off=120×0.02=2.4 [Hz]
During acceleration: ON at 60 - 1.2 = 58.8 [Hz]
During deceleration: OFF at 60 - 2.4 = 57.6 [Hz]
